Multinational mining and metals processing group Sibanye-Stillwater has welcomed the announcement of a preliminary affirmative determination by the US Department of Commerce (DoC) regarding the antidumping duty investigation into imports of unwrought palladium from Russia.

The preliminary determination references antidumping duty rates of 132.83% on imports of unwrought palladium from Russia, which is effective upon the decision’s publication in the Federal Register, which could occur as early as next week.

This tariff is subject to final determinations by the US International Trade Commission (ITC) and the DoC, which are expected to be completed in June.

The duties are expected to act as a deterrent to Russian palladium imports entering the US market, Sibanye-Stillwater points out.

This development follows the antidumping and countervailing duty petitions filed by Sibanye‑Stillwater, together with the United Steelworkers Union, in July 2025, to address Russian palladium imports to the US and to protect the long‑term sustainability of domestic platinum group metals (PGM) supply in the US, the group explains.

Between 2022 and 2024, US imports of Russian palladium increased by 35%, while palladium prices fell by 50%, it adds.

Since filing the petitions, Russian palladium imports into the US appear to have declined and palladium prices have increased materially, Sibanye-Stillwater posits.

The antidumping investigation continues alongside a countervailing duty investigation by the DoC and a concurrent injury determination by the ITC. A final outcome will be subject to further determinations by these authorities.

“We are encouraged by the commerce department’s affirmative preliminary determination and would like to thank all stakeholders who have been working tirelessly to advance this process.

“Russia’s palladium dumping has resulted in a material competitive disadvantage to the local US PGM producers and employees, and enforcement of US trade laws enables our US PGM operations to compete on a more level playing field against other, less regulated regions,” says Sibanye-Stillwater CEO Richard Stewart.
